These UV reactive products and pigments can be added to any craft project from resin, paint, acrylic, plastic, slime, ink and even nail polish.

Use these UV reactive powder pigments to detect sun leaks in indoor industrial applications, or mix with glow in the dark pigment to create a different glow color.
